Nuget package version mismatch on self created package

I'm trying to figure out why i get the wrong version number when using the --version flag.

I've found other answers for setting versions, and they worked somewhat, as seen here:

Then installing the nuget package, and checking versions with dotnet tool list, i get the correct version.

I'm packing the nuget package with the following command:

- dotnet pack --configuration Release -p:PackageVersion="<myversion>"

Can anyone tell me why i get a wrong version number when calling flexcmd --version ?
